Geological & Geotechnical Solutions

Geological & Geotechnical modeling solutions are services that quantify geological processes, identify natural hazards, and manage their resources. These projects have a high level of complexity and help companies to access risks, optimize resources, allow collaboration, ensure compliance to regulations, and help with analytics and reporting.

Geomodelle goal is to manipulate geological data using the latest information technology tools to obtain answers to elucidate the complexities of the Earth.

Domain modeling

Build geological models from data such as drillholes, structural geology, geophysical information, meshes, points, and polylines. Model stratigraphy, volumes, veins, and surfaces

Use surface trends to determine surfaces geometries and continuity

Model fault systems and determine their spatial relationships

Determine cutting relationships using surface chronology

Numeric modeling

• Incorporate structural data to create geological grade domains
• Model complex and arbritary anisotropies
• Visualize isosurfaces defined by numerical data
• Build interpolants and export volumes and isosurfaces between domains
• Interpolate numeric data to determine how it varies in 3D space
• Estimate resources such as mineralizations and rock excavations

Block modelling

• Determine geological limits of ore and rock types, estimating the tonnage and grades
• Generate relevant statistics for calculations and evaluations weighted by tonnage or by volume
• Data sets from blocks can be exported in a variety of formats
• Interpolation

3D Block Model

Environmental Solutions

Pollutant

There are five stages of examining a potentially contaminated site:

1. Discover

Investigate the site to confirm if the contamination exists, its location, and its extent.

2. Definition

Determine the project's scope and cost, focus on data analysis, make robust estimations in an iterative process, and incorporate more data in each step.

3. Design

Decide the engineering procedures to mitigate the problem keeping the stakeholders up-to-date.

4. Operate

Evaluate the decisions made by reviewing data and models. If necessary, resample and remodel.

5. Restore

Verify if the remediation was successful. If not, verify the strategy proposing changes or conclusion of the project if complete remediation is not feasible.

Environmental modeling is a dynamic process. Many iterative tasks are necessary to obtain the results. Also, a 3D visualization of the site, including geology, infrastructure, and contamination distribution, is decisive to contain the pollutants and remediate the contamination. Some of the tasks required and deliverables are:

• Exploratory Data Analysis
• Importing and validating data
• Domaining
• Geological and water table models
• Models of subsurface contamination plumes
• Estimations of contamination and their locations
